I read your blog post with interest. You have covered the basic theoretical framework of connectivism and constructivism. In the end you asked, "Yes, all of these are benefits of the technological aspect of connectivism, but are they not also a very strong component of constructivism?" They are! long before connectivism, CoP was the key phrase. And both capitalizes on social construction of knowledge. Technology provides the access to connecting with other people who share the same interests. Constructivism is more grounded to providing you solid evidence of learning; that learning was not only a result of receiving information/knowledge through your various networks but you construct new ideas based on them. If you were given a project, how would you show evidence of constructivist learning in a connected social network?
